How to grow corn?
First, the selection of land preparation.
Choose land with fertile soil, good drainage, and convenient irrigation, and prepare the land before planting to improve the porosity and air permeability of the soil, which is conducive to the growth of corn.
Second, choose the variety.
Choose high-quality, high-yielding, disease-resistant corn varieties that are suitable for the local climate and soil conditions, such as hybrid corn or conventional corn.
3. Sowing. Sowing is carried out at a suitable soil temperature, generally by mechanical sowing or manual sowing. The sowing depth should be suitable, generally 5-10 cm, and it should be adjusted appropriately according to factors such as soil moisture and sowing time. The sowing density should also be reasonably arranged according to factors such as variety and soil fertility, generally 3000-4000 plants per mu.
Fourth, fertilization. Before sowing, apply plantar fertilizer, mainly organic fertilizer, and add an appropriate amount of phosphate and potassium fertilizer. During the growth period of corn, top dressing is carried out according to the plant growth and soil fertility conditions, which are generally divided into seedling fertilizer, jointing fertilizer and ear fertilizer. When topdressing, we should pay attention to the amount of nitrogen fertilizer used to avoid excessive use and lead to the growth of corn plants.
5. Irrigation Autumn and Winter Check-in Challenge Corn needs sufficient water to grow, and it should be irrigated in time during the growing period, especially during dry periods. The irrigation method can adopt water-saving irrigation methods such as sprinkler irrigation or drip irrigation, and make reasonable arrangements according to factors such as soil moisture and climatic conditions. 6. Weeding and pest control should be weeded in time during the growth of corn, and manual weeding or chemical herbicides can be used. At the same time, attention should be paid to the prevention and control of corn diseases and insect pests, such as corn borer, aphids, etc., which can be combined with biological control and chemical control.
7. Harvesting and storage.
Corn should be harvested in time after maturity to avoid mildew and yield reduction caused by long-term stacking in the field. After harvesting, it is necessary to dry, dry and other treatments to reduce the moisture content and facilitate storage and transportation. The storage location should be selected in a dry, ventilated and moisture-proof place to avoid problems such as moisture, mildew and rodent infestation.
